Plants of the "cyclone" type are used in industry for the purification of gases and liquids. The principle of operation of the filter is based on the physical laws of inertia and gravity. Air (water) is sucked out of the device through the upper part of the filter. A vortex flow is created in the filter. As a result, the contaminated product enters the filter through the branch pipe located on the side of the upper part. Since the particles of debris are heavier, they settle in the lower part of the filter, and the cleaned product is discharged through the upper part. It is such a filter, made for the workshop, that we will consider today together with the author of the homemade product.

For the inlet and outlet, the author used a plastic pipe with a diameter of 7.6 cm, as well as two couplings for it.
First, he makes an inlet. Cuts off a piece of 23 cm from the pipe. Cuts the sleeve in half. He cuts a rectangle out of plywood with sides of 12.5 and 15 cm.Cuts a hole 8.9 cm in the middle ( outside diameter couplings). Having inserted a pipe into the hole, it fixes it with a coupling on both sides. Seals the seam with hot melt glue.

To the side wall of the rectangle (12.5 cm), fasten a cut piece measuring 12.5 by 20 cm.

Then the author cuts the pipe and plywood so that the curvature of the trim matches the curvature of the cylinder.

Attaching the structure to the installation site, it makes measurements for the manufacture of a vertical support. Cutting it out, attaches it to the body. Fastens where the cylinder seam goes, thus closing it.

Marks the location of the inlet cutout on the polycarbonate. Cuts it out with a drill.

Installs the inlet pipe into the hole, secures it. The seam is sealed with hot melt glue.

Then it makes an outlet pipe. Cuts off a piece of pipe 15 cm. Inserts it into the hole in the top cover. Installs a coupling on both sides. It processes with hot melt glue.

The author made the lower screen from MDF. Screen size 46 cm in diameter, thickness 3 mm. Draws a circle at a distance of 5 cm from the edge. Measures an angle of 120 degrees. Cuts the strip between the sides of the corner. Screws the screen to the bottom cover so that the cutout starts just behind the inlet pipe.

When working in a workshop or at home with a grinding tool, when processing parts and preparing surfaces, there is a need to remove fine dust. And, of course, it is desirable to reduce its concentration even during work by organizing a local constant air purification at the workplace.

At enterprises, this problem is solved by installing filtration units with a cyclone, which collects and settles dust with the required efficiency.

In our case, it is enough make a vacuum cleaner with a cyclone, thereby saving on the purchase of a construction vacuum cleaner, where such a function is provided by the manufacturer.

The principle of operation of a homemade construction vacuum cleaner with a cyclone filter

There are several options for making a cyclone for domestic needs. To determine the most effective scheme the functioning of the equipment, you should know the principle of operation of this filter.

The cyclone in the classic version is a cylinder and a cone, in the upper part of which there is an inlet for polluted air and an outlet for cleaned air.

The inlet is made so that air enters the filter tangentially, forming a rotating flow directed towards the equipment cone (downward).

Inertial forces act on the particles of pollutants, carry them out of the stream to the walls of the apparatus, where the dust settles.

Under the influence of gravity and secondary flow, the mass deposited on the walls moves to the cone and is removed to the receiving hopper. The cleaned air rises up along the central axis and is discharged through a branch pipe located strictly in the center of the upper platform of the cyclone.

A prerequisite effective cleaning air is an accurate calculation of the apparatus and the tightness of the cyclone, including in relation to the receiving hopper.

Otherwise, the principle of operation is violated and chaotic air movement occurs, preventing dust from settling in normal mode.

In addition, it is necessary to select an engine that sucks in polluted air, which will provide optimal parameters for the operation of the equipment.

Homemade filter for a construction vacuum cleaner, the options of which are offered on the Internet cannot be called a full-fledged cyclone.

The most simple circuit of such equipment is a plastic barrel with an embedded tangential inlet pipe, mounted with a filter from the car inside the "cyclone" body, through which purified air is removed and to which a household vacuum cleaner is connected.

The disadvantages of the equipment are the absence of a formed flow swirling along the walls of the barrel and a laminar return flow.

In fact, we get an additional capacity for the deposition of large particles (sawdust, shavings), and fine dust will clog the outlet filter and will need constant cleaning.

To improve the design, we suggest adding a plastic barrel homemade cyclone made from a traffic cone. It is best, if the work is being carried out for several hours, to install stationary option equipment for removing dust from the workplace.

In this case, we need a radial household fan. And with a one-time connection of the cyclone, it is enough to use a conventional vacuum cleaner with suction power control.

Sometimes an additional rheostat is installed to reduce the rotational speed of the vacuum cleaner motor, thereby selecting the parameters necessary for the normal functioning of the filter.

In the following sections of the article, we will present you two options for a cyclone for domestic use.

Selection of inventory - what is required for work

For the first design option for a stationary installation, you need the following components:

• Plastic barrel;
• Gray plastic sewer pipe with a diameter of 50 mm;
• Road cone;
• Corrugated hoses, steel wire reinforced or metallized hoses;
• Adhesive for plastic;
• Radial household fan with the ability to change the engine speed and performance equal to six-fold air exchange in the room;
• Plywood 10-12 mm thick.

The second version of the product is the most successful, since in this case the product approaches the functionality of a real cyclone.

To make a filter, you will need to purchase:

• Ready-made plastic cyclone made in China;
• A barrel, bucket or other container for the manufacture of a dust bin;
• Corrugated hoses.

A plastic cyclone is inexpensive, about 1,500-2,500 rubles, and is designed to collect dust of medium and heavy fractions. Copes well with shavings and sawdust.

Step-by-step instructions for the cyclone assembly process

The first option is next in line stationary structure for workshops with a large formation of dust of various origins.

Assembling a cyclonic filter for a vacuum cleaner

1. First, we make the cyclone itself. In the plastic cone we make a hole for the passage sewer pipe tangentially.
2. For a better connection of the branch pipe with the body of the cone, the mating surface is matted with an emery cloth. We carry out gluing of the seams using an assembly gun.
3. In the upper part of the cone, we install a vertical pipe, the lower end of which should be below the inlet. Thus, we will be able to achieve a vortex movement of air. The branch pipe is fixed in a plywood sheet in the shape of a circle with a diameter equal to the size of the base of the cone.
4. The prepared cyclone is fixed to the barrel lid using a round plywood sheet.
5. To prevent the plastic barrel from deforming under the influence of vacuum when clogging the inlet pipe with debris, we install a spacer inside the container - a frame made of plywood sheet. External dimensions frames repeat the inner diameter of the barrel. To strengthen the structure, we pull the building cone to the container lid using metal pins.
6. Next, we connect the cyclone to corrugated hoses at the entrance and exit. We install a radial household fan outdoors under a canopy.

The second version of the construction vacuum cleaner is based on a Chinese plastic cyclone, which is also fixed on any of the selected containers. The result is a reliable and efficient design.
The cyclone is attached to the tank using a clamping metal flange.

VIDEO INSTRUCTION

When starting the vacuum cleaner and further operation, do not forget to clean the inlet pipe and stop the internal spacers on the containers in order to prevent deformation of the receiving hopper.

If a finer air purification is required, then the design is complemented by an automobile filter in the housing at the outlet of the product.

When processing wooden blanks, everyone probably came across the fact that everything around is covered big amount shavings, sawdust and wood dust. To get rid of them at least partially, they use various dust collectors, chip extractors, filters and other devices. Many power tools and machine tools have their own dust collectors, while others have special outlets for connecting a vacuum cleaner.

In home workshops, it will be better to use specials. a vacuum cleaner than a household one. Firstly, the engine in the special. the vacuum cleaner is designed for more than long-term operation, and secondly, as a rule, it is equipped with a hose with a length of 3 m, which greatly simplifies its use with a power tool. And yet, the disadvantage of each vacuum cleaner is a small container for garbage.

How to make a cyclone filter with your own hands

With the goal of somehow simplifying the work of cleaning the vacuum cleaner and reducing the cost of bags, I began to collect information on this issue. Found a description on the Internet different types simple devices in the form of intermediate dust collectors for a vacuum cleaner. Firstly, these are dust collectors in the form of a mini-cyclone. They do a good job of collecting dust in a separate container, preventing it from getting into the vacuum cleaner, which increases the service life of the bags tenfold. The process of cleaning the dust collector from debris is also facilitated. Ready-made fixtures are sold through online stores, but their cost is quite high with a very simple design.

Design. I decided to make a mini cyclone type dust collector myself. The author and developer of this design is considered Bill Pentz from California. Having earned himself a serious allergy to fine wood dust, he subsequently devoted a lot of time and energy to combating both the disease itself and its causes.

The dust collector is a device, the main element of which is an inverted truncated cone, inserted in the lower part into a container for collecting dust. A tube for connecting to a vacuum cleaner is inserted into the upper part of the dust collector, and a tube for connecting a hose from the tool is inserted at the side tangentially.

When the vacuum cleaner draws in the air inside the apparatus, vortices are formed, and the debris, moving with the air, is thrown by centrifugal forces to the inner walls of the filter, where they continue to move. But as the cone narrows, the particles collide more often, slow down and, under the influence of gravity, fall into the lower container. And the partially purified air changes direction and exits through a vertically installed pipe and enters the vacuum cleaner.

There are two mandatory requirements for a given construction. This is, firstly, its tightness, otherwise there will be a sharp loss of suction power and air purification quality. And, secondly, the rigidity of the container and the cyclone body itself - otherwise, it strives to flatten.

There are tables on the Internet with drawings of cyclones for particles of various sizes. The cyclone body can be made from galvanized or plastic, or you can choose a ready-made container of a similar shape. For example, I've seen cyclones made on the basis of a traffic cone (necessarily rigid), a plastic flower vase, a tin horn, a large toner tube from a copier, etc. It all depends on what size the cyclone is needed. The larger the particles of debris, the larger the diameter of the tubes for the connected hoses, and the more massive the cyclone itself is.

Bill Pentz points out some of the design features. So, the smaller the cyclone in diameter, the greater the load on the vacuum cleaner. And if the receptacle is low and flat, then there is a likelihood of garbage being sucked out of the receptacle and getting into the vacuum cleaner. When using a container of any shape, it must not be filled up to the top with garbage.

The choice of material. I decided to use plastic pipes as blanks for outdoor sewerage and fittings for them. Of course, it will not be possible to create a full-fledged cone from them, but I was not the first who tried to use them for this purpose. The advantage of this choice is the rigidity of the parts and the tightness of their joints due to the seals. Another plus is that there are various rubber pipe fittings that allow you to easily and tightly connect the vacuum cleaner hose. In addition, if necessary, the structure can be easily disassembled.

For my own collection of large sawdust and shavings, I made a cyclone from a pipe ∅160 mm. I used pipes ∅50 mm as connectors for hoses. I would like to draw your attention to the fact that the eccentric adapter from a pipe ∅110 mm to ∅160 mm must necessarily be funnel-shaped. I've seen flat ones, but they won't fit - they won't work, and the debris will get stuck.

Do-it-yourself cyclone work progress

Operating procedure. In the plug for the pipe ∅160 mm and the pipe of the body, I made holes for the bends for the hoses. Then, using a thermal gun, I glued a piece of pipe ∅50 mm into the plug. It should be located in the middle of the cyclone body and be a couple of centimeters below the side tube, so it is better to first glue the longer tube into the plug, and then cut it in place during assembly.

On the Internet, I found complaints that hot melt glue does not stick to PVC pipe, and advice to weld parts with a soldering iron and pieces of the pipe itself. I tried it but didn't. Firstly, my glue adhered perfectly, and, secondly, the smell of molten plastic discouraged any desire to weld anything in this way, although the connection may be more durable and neat.

The difficulty of working with hot melt glue is that it does not spread, and the seam in the absence of skills is not very even. I had such a sad experience - to align the seam, I decided to heat it up with a hairdryer. I got a smooth surface of the glue bead, but at the same time the plastic tube itself was deformed, and it had to be thrown away.

In the next step, I glued to inner surface the housing is a spiral, which should direct the air flow down to the dust collector. This solution was recommended by Bill Pentz himself - according to him, it almost doubles the efficiency of the cyclone. A spiral with a height of about 20% of the gap should fit snugly against the body and make one turn with a pitch equal to the diameter of the inlet for the side pipe.

As a material for it, I used a plastic rod, which I heated with a hairdryer and bent in the shape of a spiral (photo 1) and then pasted it into the case (photo 2) using a thermal gun. Then pasted the side tube (photo 3), the inner end of which is directed slightly downward.

As soon as the glue cooled down and hardened, I measured and cut the vertical outlet tube so that it was 2-3 cm below the edge of the side tube, and finally assembled the entire structure.

Waste container made of tough plastic barrel, to the bottom of which I attached the wheels - it turned out to be very convenient for cleaning it (photo 4)... I cut a viewing window on the side of the barrel and closed it with acrylic glass on hot melt glue. From above, reinforced the connection with a plastic ring and bolts. It is convenient to monitor the filling of the container through such a porthole.

I didn't have a barrel lid, and I made it from a piece of countertop that waited a long time in the wings after the sink in the kitchen (photo 5)... On the underside of the tabletop, I chose a groove for the edges of the barrel with a milling cutter and glued a window seal into it for a tight connection (photo 6)... According to the rules, the hole in the lid should be made in the center, but then I would have problems with placing the cyclone in the workshop, so I made a hole with an offset. The lid is attached to the barrel with latches from a long-broken vacuum cleaner. He also used a hose to connect the cyclone. I would like to draw your attention to the fact that it is better to take hoses from vacuum cleaners. If we take, say, corrugated pipe for electrical wiring, when the vacuum cleaner is turned on, a whistle and eerie noise appear.

Do-it-yourself cyclone for a vacuum cleaner

Connecting the cyclone to the instrument. Not all tools have an outlet for a vacuum cleaner. So I decided to make a simple, adjustable holder for the vacuum hose. For him, I made blanks for levers from scraps of plywood (photo 7)... The holder is supplemented with a sewer clamp for fastening the hose (photo 8)... The stand was specially made large sizes so that it is possible to secure it with a clamp or hold it with a load. The holder turned out to be convenient - I use it not only for the vacuum cleaner hose, but also for a portable lamp, laser level and support the long workpiece in a horizontal position.

After assembling the cyclone, I conducted several experiments to determine its efficiency. To do this, I sucked in a glass of fine dust, after which I measured its volume that got into the container of the dust collector. As a result, I was convinced that about 95% of all garbage gets into the barrel, and only very fine dust, and even a small amount of it, gets into the vacuum cleaner bag. I am quite satisfied with this result - now I clean the bag 20 times less often, and only from fine dust, which is much easier. And this despite the fact that my design is far from perfect in form and proportion, which, of course, lowers the efficiency.

Wiring. After checking the cyclone's performance, I decided to make a stationary wiring of the hoses around the workshop, since the three-meter hose is certainly not enough, and the vacuum cleaner with the cyclone is bulky and clumsy, it is inconvenient to move them around the workshop every time.

Due to the fact that standard pipes were used, it was possible to mount such a wiring in an hour. I pushed the vacuum cleaner and the cyclone into the farthest corner, and laid pipes ∅50 mm through the workshop (photo 9).

In the workshop I use a specialized green series BOSCH vacuum cleaner. After four months of operation, it is paired with a cyclone, I can say that in general they are coping with their task. But I would like to slightly increase the suction power (when working with a jigsaw, you have to move the hose almost close to the cutting zone) and reduce the noise level. Since little chips get into the vacuum cleaner itself, there is an idea to make a more powerful impeller and take it outside the workshop to the street.

I can also say that the suction power of the vacuum cleaner dropped a little when using it with a cyclone, but at work this is not very noticeable. There were doubts that static electricity can accumulate on the elements, because the entire structure is plastic, but this practically does not happen, although earlier, when collecting fine dust, the hose had to be grounded.

Of course, when using professional pipelines with large outlets, this diameter is not enough. It is better to take ∅110 mm or more, but then both the vacuum cleaner and the cyclone should be more powerful. However, this is quite enough for my homework.

The vacuum cleaner hose was rigidly fixed on a small pipe bend ∅50 mm and inserted into the right place wiring. At the same time, the rest of the wiring exits are closed with plugs rigidly put on short bends. Moving the hose is a snap.

During operation, I ran into one small problem. If a small pebble falls into the hose (my concrete floors have not been repaired for a long time) or another small but heavy object, it moves through the pipes to the vertical section in front of the cyclone and remains there. When such particles accumulate, other debris clings to them and can form a blockage. Therefore, in front of the vertical section of the wiring, I cut a camera from a pipe ∅110 mm with an inspection window. Now all heavy debris is collected there, and by unscrewing the lid, it is easy to get it out. This is very convenient when fasteners accidentally fall into the vacuum cleaner or small detail... here is simple - I unscrew the lid, turn on the vacuum cleaner and use my hand to mix everything that is left in the revision. Small particles immediately fly away into the cyclone tank, while large ones remain and are easily removed. Their number is usually insignificant, but recently I found a missing screwdriver bit in such garbage.

Also, the revision hole can be used to temporarily connect a 100 mm hose. It is enough to unscrew the lid - and we get a finished hole ∅100 mm. Naturally, in this case it is necessary to muffle all other wiring inputs. Flexible adapter can be used to simplify connection (photo 10).

To remotely turn on the vacuum cleaner, next to the hose clamp, I installed a switch (photo 11) and additional. It can be used to connect a power tool, then you will definitely not forget to turn on the vacuum cleaner before using the tool - this often happens to me.

I regularly use all of these devices. I am satisfied with the result - there is noticeably less dust in the workshop, and it is easier to clean. During this time, I collected several bags of sawdust, and very little debris accumulates in the vacuum cleaner. I want to test a cyclone for collecting small garden debris and dust when cleaning a concrete floor.

I think this design very useful and affordable for making at home.

Sergey Golovkov, Rostov region, Novocherkassk

Recently, I got carried away with working with wood and the question of removing shavings and sawdust arose very sharply. So far, the issue of cleaning the workplace is being solved with a home vacuum cleaner, but it quickly clogs up and stops sucking. We often have to shake out the bag. In search of a solution to the problem, I reviewed many pages on the Internet and found something. As it turned out, completely workable dust collectors can be made from scrap materials.

Mini vacuum cleaner from a plastic bottle

Here is another idea for a mini vacuum cleaner based on the Venturi effect.
such a vacuum cleaner works from the forced air.

Venturi effect

The Venturi effect is the drop in pressure when a stream of liquid or gas flows through a constricted part of a pipe. This effect is named after the Italian physicist Giovanni Venturi (1746-1822).

Justification

The Venturi effect is a consequence of the action of Bernoulli's law, which corresponds to the Bernoulli equation, which determines the relationship between the velocity v fluid, pressure p in it and in height h, on which the considered fluid element is located, above the reference level:

where is the density of the liquid, and is the acceleration of gravity.

If the Bernoulli equation is written for two cross-sections of the flow, then we will have:

For a horizontal flow, the middle terms in the left and right sides the equations are equal to each other, and therefore are canceled, and the equality takes the form:

that is, with a steady horizontal flow of an ideal incompressible fluid in each of its sections, the sum of the piezometric and dynamic pressure will be constant. To fulfill this condition, in those places of the flow where the average fluid velocity is higher (that is, in narrow sections), its dynamic head increases, and the hydrostatic head decreases (and therefore the pressure decreases).

Application
The Venturi effect is observed or used in the following objects:

• in water jet pumps, in particular, in tankers for products of the petroleum and chemical industries;
• in burners that mix air and flammable gases in the grill, gas stove, Bunsen burner and airbrushes;
• in Venturi tubes - constriction elements of Venturi flow meters;
• in Venturi flow meters;
• in water ejector-type aspirators, which create small vacuum using the kinetic energy of tap water;
• sprayers (sprayers) for spraying paint, water or air fragrance.
• carburetors, where the Venturi effect is used to suck gasoline into the inlet air stream of an internal combustion engine;
• Automated swimming pool cleaners that use water pressure to collect sediment and debris
• in oxygen masks for oxygen therapy, etc.

Now let's look at the samples that can take their rightful place in the workshop.

Ideally, I would like to get something similar to a cyclone filter, but from scrap materials:

Homemade chip separator.

The principle is the same, but made much simpler:

But this option I liked the most, since it is a reduced analogue of an industrial cyclone:

h1

Since I do not have a traffic cone, I decided to stop at just such a structure, assembled from plastic pipes for sewerage. A definite plus is the availability and low cost of material for assembling the structure:

Homemade cyclone made of plastic sewer pipes

Please pay attention to the mistake made by the master. The garbage pipe should be positioned like this:

In this case, the required vortex will be created.
The following video shows a similar design at work:

And finally, a slightly modified version:

If a person has his own workshop, then one of the most important issues is cleaning the premises. But unlike cleaning dust in an apartment, an ordinary household vacuum cleaner will not help here, since it is not designed for debris and sawdust - its garbage container (dust collector or bag) will clog up very quickly and become unusable. Therefore, a homemade cyclone filter is often used, which, together with a household vacuum cleaner, will help clean up the workshop.

Introduction

Wood dust and other technical debris, although it seems harmless at first glance, in fact, are fraught with many different dangers, both for the master and for the equipment. For example, continuous operation without protective equipment to prevent dust from entering the respiratory system can cause serious complications. respiratory tract, impair the sense of smell, etc. In addition, the tool that is in the workshop under the influence of dust can quickly fail. This is due to the fact that:

1. dust, mixing with the lubricant inside the tool, forms a mixture that is completely unsuitable for lubricating moving parts, which as a result leads to overheating and further breakdown
2. dust can impede the rotation of the moving parts of the tool, which leads to additional loads, overheating and failure,
3. dust clogs the air ducts designed to ventilate the heated parts of the tool and remove heat from them, resulting in overheating, deformation and failure of them again.

Thus, the issue of the quality of removal of sawing products and, in general, cleaning the room is very acute. Modern power tools are equipped with systems for removing dust and chips directly from the sawing area, which prevents dust from spreading throughout the workshop. In any case, a vacuum cleaner (or chip sucker) is needed for the dust removal process!

There are good industrial vacuum cleaners and if possible, it is better to choose the most the best option for the price and quality and buy a construction vacuum cleaner.

Nevertheless, there are times when there is already a household vacuum cleaner and it is easier to upgrade it and solve the problem of collecting construction waste indoors. To do this, you need to use a cyclone filter - it is done in half an hour with all the necessary elements.

Principle of operation

There are a great many different designs of cyclones, but all of them are united by the same operating principle. All designs of cyclonic chip suckers consist of three main parts:

• Household vacuum cleaner
• Cyclone filter
• Garbage collection container

Its design is such that the flow of the intake air is directed in a circle and its rotational movement is obtained. Accordingly, a centrifugal force acts on the construction waste contained in this air stream (these are large and heavy fractions), which presses it against the walls of the cyclone chamber and, under the action of gravity, it gradually settles in the tank.

The disadvantage of a cyclonic vacuum cleaner is that in this way only dry garbage can be collected, but if there is water in the garbage, then there will be problems with the suction of such a substance.

The vacuum cleaner must be powerful enough, since in its normal operation it is supposed to suck in air through a standard hose. If an additional cyclone filter is used, an additional filter appears in the air path, and the total length of the duct is more than doubled due to the additional duct. Since the design is as maneuverable as a separate vacuum cleaner, the length of the last hose should be sufficient for comfortable work.

Preparatory work

As mentioned above, you can make a cyclone filter for a workshop in half an hour, but for this you need to check the availability of everything you need for the production of a chip sucker with your own hands, namely: tools, materials and consumables.

Instruments

For the production of work, tracking tools will be needed:

1. electric drill,
2. screwdriver,
3. jigsaw,
4. compass,
5. clamps,
6. Phillips screwdriver,
7. pencil,
8. for wood (50-60mm),
9. kit .

Materials and fasteners

Materials can be used both new and used, so carefully review the list below - you may already have something in stock;

1. The air duct (hose) for the vacuum cleaner is corrugated or in a textile braid.
2. A sewer pipe with a diameter of 50 mm and a length of 100–150 mm, at one end of which the air duct of your household vacuum cleaner must be inserted.
3. Sewer outlet 30 or 45 degrees, 100-200 mm long, at one end of which the air duct specified in clause 1 will be inserted in the future.
4. Bucket ("large") plastic 11-26 liters with a hermetically sealed lid.

Making a cyclone filter

Creating a homemade chip sucker consists of a number of stages:

1. Create anchor ring and curly insert
2. Installing the retaining ring
3. Installing the side pipe
4. Top entry setting
5. Installing curly insert
6. Assembling the cyclone filter

Create anchor ring and curly insert

It is necessary to cut off the side of the small bucket, which is used to fasten the lid. As a result, you should get such a cylinder (well, a little on a taper).

We do the markup - we put a small bucket on and draw a line along the edge - we get a circle.

Then we determine the center of this circle (see the school geometry course) and mark out another circle, the radius of which is 30 mm larger than the existing one. Then we mark out the ring and the curly insert, as shown in the figure.

Installing the retaining ring

We fix the ring on the edge of the small bucket so that we get a side. We fix it with self-tapping screws. It is advisable to pre-drill the holes so as not to split.

We mark the roof of the large bucket. For marking, you need to put the bucket itself on the lid of a large bucket and circle its outline. It is better to do the markings with a felt-tip pen, since the trace is clearly visible.

It is important to note that all joints must be sealed, respectively, before installing the cover, you need to coat the joint with sealant. You also need to grease the junction of the wooden ring and the small bucket.

Installing the side pipe

The side pipe is made from a sewer outlet of 30 degrees (or 45 degrees). To install it, you need to drill a hole in the top of the small bucket with a crown. Note that the bottom of the small bucket is now the top.

Top entry setting

To make the top entry, you need to drill a hole in the upper part of the chip sucker (small bucket), that is, in the center of the former bottom.

To firmly fix the inlet pipe, you need to use additional element strength in the form of a 20 mm thick square billet with a central hole for a 50 mm branch pipe.

The fixing of this workpiece is carried out from below with four self-tapping screws. Before installation, for tightness, the joint must be coated with sealant.

Installing curly insert

The shaped insert is a very important component of a homemade chip sucker, it must be fixed inside the cyclone filter, as shown in the photo.

Assembling the cyclone filter

Then it is necessary to correctly connect the air ducts:

1. Upper branch pipe - to a household vacuum cleaner
2. Angled elbow entering at an angle from the side - to the hose.

Homemade cyclone vacuum cleaner(chip sucker) is ready.
